I think the AD inspections and established intervals will remain in force for some time to verify findings if nothing else. The final report is awaited of course but it may be that RR have effectively concluded their investigation.
It looks as though the precautionary high thrust/cycles limitation has been lifted - not that we know much about the restriction directly.
I think that whatever gremlin might be dreamt up by we speculators, RR, their peers and the accademics with whom they collaborate will have most likely written the book on the subject many yeas ago. So I am not a skeptic.
